FORT WORTH (CBSDFW.COM/AP) - Heavy rain and strong winds continued to batter North Texas on Wednesday morning, as the entire DFW area was completely soaked before sunrise. Parts of the Metroplex began getting hit with storms on Tuesday night, and the downpour remained constant throughout the overnight hours. (Click here for photos of the severe weather and flooding)

Flooding has been the biggest concern. With so much rain falling in such a short frame of time, DFW roads — especially those in near creeks and lakes, or in low-lying areas — have been rendered dangerous or completely impassable. Drivers are urged to take extreme caution, obey any posted road blocks or closures and be mindful of unblocked areas that appear to have high water. A Flash Flood Watch was put into effect until Wednesday afternoon for much of North Texas, as storms pivot in from the south. (Click here to check the latest traffic conditions.)

Some southeastern areas — Navarro County, Henderson County, Anderson County — are also under a Tornado Watch. There will likely be a few strong storm cells with damaging winds, but the greatest threat for severe weather remains south of these counties. (Click here to check the latest watches and warnings.)

Oncor reported more than 9,100 power outages across the state, with most being in the Central Texas area toward Austin. Power has since been restored to nearly 1,000 of those customers. At one time, CenterPoint Energy in Houston had more than 20,000 customers without electricity early on Wednesday morning. That number has since dwindled down to about 7,700.

About 60 early morning flights were canceled at DFW International Airport due to the rain and lightning across the area, according to airport spokesman Dave Magana. Additional flights are expected to be canceled or delayed as the day continues. The ground crews at the airport are unable to work on the runway in such hazardous conditions.
